Lowering the arse!

[lambrettatastic]

I’ve recently fitted a lowered front end , and knowing I had adjustable spring plates at the back , thought this would be an easy job to get the back down a touch to level the bus out…but no!
The adjusters are fully wound out,so it looks like I need to fettle it on the splines.
So the question is having watched a few how to vids, when I detach the spring plates do I have to disconnect the brake pipe? I’m hoping not as just having fitted discs up front, I’ve had all the brakes bleed..

I would. It's not a major task to bleed the breaks if you are planning on pulling the spring plates.

You don’t need to do any of that with adjustable springlates. The section on the splines comes off separately - just move it round a notch and re fit. Biggest hassle will be taking the wheel off.

This document from Creative engineering explains exactly how to re-index just the splined portion, without removing the main trailing arm.
Just as Clem has outlined.
Last two paragraphs tell you how.

Its a job i need to do on one side of ours. someone got one side at least a spline out, so i had to balance just for now using the grubscrew fine tuners.

You were right… taking the wheels off was the longest job… and cleaning everything once off.
One concern, the torsion bars are different lengths… is that right??

No, they're the same length.

Thanks sparky…so is it right that one protrudes more than the other?

Just needs tapping back in.
They sit in a splined socket in the centre of the rear housing, if you knock one through too far it pushes the other one out.

Once again … thanks for the help, all part of my learning .
Got the bus sitting how I want… but no travel at all on the back shocks, so need to get new.
